Retroactive airdrops are one of the easiest ways to earn free crypto. Learn how testnets work, why projects give free tokens, and how you can claim them step by step.
What Is a Testnet?
A testnet is a blockchain testing environment that simulates the real network (mainnet). Projects launch testnets to test security, new features, and get feedback from early users.
Popular testnets: Ethereum Goerli, Optimism, ZKSync, LayerZero.
What Is a Retroactive Airdrop?
A retroactive airdrop means a project rewards early testers/users with free tokens after the mainnet launch. Examples: Uniswap, Optimism, Arbitrum, Starknet.
It’s legit because it incentivizes early adoption and supports fair community growth.
